deceased Application June 30, 1937, Serial No. 151,264 1 Claim. (o1. 72-102) This invention relates to a wall structure.

The invention aims to provide, in a manner as hereinafter set forth, a mortarless composite wall structure of interengaging bonded together ele- 5 ments forming a single unit and acting when used in buildings as a protective medium for health, as well as against wind, blasts, explosions, frost and dampness.

The invention further aims to provide, in a manner as hereinafter set forth, a wall structure which when employed in the construction of buildings, will form unusually strong and elastic buildings.

The invention further aims to provide, in a manner as hereinafter set forth, a wall structure which, when employed in building construction, will not only increase the life of the building, but also will be sound proof, fuel saving, and noncracking from heavy traffic.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a wall structure which is simple in its construction and arrangement, strong, durable, compact, readily assembled, thoroughly efiicient in its use and comparatively inexpensive to set up.

To the above ends essentially the invention consists of such parts and such combination of parts as will be hereinafter more specifically referred to and illustrated in the accompanying drawings wherein is shown embodiments of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

Figure 10 is a section on line Ill-4 El, Figure 9. A wall structure in accordance with this invention includes a series of superposed courses of wall block elements, a series of superposed rows of jointing elements interengaging with the wall block elements and a mortarless bond for the block and jointing elements. The wall block elements may be of the form shown in Figure l or Figure 5 or that shown by Figure 7. The jointing elements may be of the form'shown in Figure l. or Figure 5 or that shown in Figure 7. The discharge end of the brick machine shown in Figures 8 to 10 may be of the form to provide the. blocks of a construction similar to that shown in Figures 1, 5 and 7.

With reference to Figures 1 to 4, the full size wall block elements are generally indicated at l2 and the end or half size wall block elements at 53. In the form shown in Figures 1 to l, the jointing elements are generally indicated at i l and the bond at 95. The elements l2 and 53 are of like form, with this exception, that the element I3 is one-half the size of the element 13.

The wall block elements are arranged in superposed courses separated by the bonds E5. The wall block elements of an upper course are disposed in staggered relation with respect to the wall block elements of a lower course. The jointing elements are arranged in superposed rows. The jointing elements of each row are disposed in endwise relation and .are separated from each other and'from the block courses by the bond l5. The latter is positioned against the non-exposed. surfaces of the wall block elements and jointing elements. When the wall is set up the outer ends of the rows of the jointing elements are flush with the outer ends of the courses of the wall block elements.

The element !2, as well as the element iii includes a body part l8 formed in its upper and lower faces ll, 18 with oppositely disposed grooves I9, 28 respectively. The groove 69 is of rectangular or U-shaped contour and the groove 26 is of rectangular or inverted U-shaped contour. The depth and width of the grooves l3 and 29 are the same. The grooves i9, 20 extend from one end to the other end of the body part it and are intersected centrally by the longitudinal median of the body part. The latter adjacent the side walls of the grooves i9, 20 is formed therein with permanently open channels 2i of rectangular cross section extending from end to end thereof. The channels in the body part of one block of a course align with the channels of the body parts of the other blocks of the course.

The jointing elements [4 are of rectangular contour. The grooves in the upper face of the wall block elements of a lower course lengthwise align with the grooves in the lower face of the wall block elements of an upper course to coact therewith to thereby provide a channel between a pair of courses extending from end to end of these latter.

The jointing elements M are rectangular in cross section and correspond in length to the length of a body part of a wall block element. The jointing elements of each row are disposed in endwise alignment and each row of jointing elements is arranged within achannel between a pair of courses. Each jointing element is of a length to correspond to that of a body part of a wall block element l2. When a jointing element i4 is set up, one-half of the'length thereof is arranged in a pair of aligned upper grooves in a pair of wall block elements of a lower course and the other half of the jointing element is arranged in the lower grooves of a pair of block forming elements of an upper course.

The wall block elements and jointing elements are formed from any suitable material capable of being molded. The preferred dimensions for the wall block elements vary from the size of the standard brick to a size twelve by twelve inches. In the smaller size wall block elements it will be necessary to use a jointing element small enough to not require the grooves of the wall block element to be of a depth to weaken the block elements. When the larger size wall block elements are employed the jointing element will correspond in size to that of the regular size brick.

The bond which is of the paste-like type may also be termed a filler and it will consist of limemilk cement, barium sulfate, asbestos powder, magnesite, and peet, or in lieu of peet wood wool or fine sand may be employed. The bond l5 when applied to the block or jointing elements forms the wall as a single unit. The bond as referred to is of the mortarless type. I

With reference to Figures 5 and 6, the wall block elements are indicated at 22, 23, the latter being of the same construction as the element 22 with the exception that it is just one-half the size thereof. The outer side faces of the blocks 22, 23 are formed with grooves, as at 24, 25 to provide for the simulation of bricks and half bricks. The block 22, as well as the block 23 includes a body portion 25 formed centrally of its upper and lower faces with oppositely disposed semi-circular grooves 25, 21 respectively. The grooves 26, 21 extend from one end to the other end of body part 25 and are intersected centrally by the longitudinal median of the body part. The latter is formed lengthwise thereof and from end to end with a pair of permanently open circular channels 28 in proximity to its sides. 7

The grooves 26 of the blocks of the lower course coast with the grooves 21 of an upper course to provide a channel arranged between and extending from end to end of such courses. The arrangement is such that there is a channel between each pair of courses. The channel provided between the coaction of the grooves 26 with the grooves 21 is of circular contour.

I'he jointing element shown in Figures 5 and 6 and indicated at 29 is of circular cross section.

The joining elements 29 are arranged in rows. The jointing elements 29 of each row are disposed in endwise alignment. Each row of jointing elements 29 is arranged within a channel between a pair of courses and the row extends from one end to the other end of said courses.

The bond shown in Figures 5 and 6 is indicated at 39. The bond separates the wall block elements of each course, separates a lower course from an upper course, separates the jointing elements 29 of each row and separates the jointing elements of a row from the wall of a channel in which the row is positioned. The bond 30 is applied throughout the non-exposed surfaces of the Wall block forming elements and the jointing elements.

With reference to the form of wall block element 3! and jointing element 32 shown in Figure 7, the element 3! is of the same form as an element l2 but in lieu of providing element 3| with the channels 2! it is formed centrally thereof and from end to end with an enlarged channel 33.

The upper and lower grooves of the element 3| are indicated at 3 4, 35 respectively and are oppositely disposed. The element 32 is of the same form as the element M.

The elements 22, 23, 3!, 32 and bond 30 are formed of the same material as that which is mployed for elements l2, I4 and bond l5.

With reference to Figures 8 to 10, the discharge end of a brick machine which is employed to produce the wall block elements is indicated at 36 and is to be provided with a molding device of a form to produce the wall block elements of a construction as shown inFigures 1, 6 and 7. By Way of example, the molding device indicated at 37 provides for a form of wall block element such as indicated at I2 and 13. The device 3'! is anchored, as at 38 to the outlet of the discharge end 3-3 of the brick machine.

The jointing elements may be termed joint locks I and act, not only to prevent the lateral shifting of the wall block elements relatively to each other, but further assist in strengthening the wall.

The bond employed would be of such nature whereby it may be readily applied with a brush.

The providing of the molding device or what may be termed a die device used in connection with a brick making machine will enable for more expeditiously producing the wall if they were manufactured block making machine now employed.

What I claim is:

In a wall construction a plurality of block members disposed in superposed staggered relation,

each of said block members comprising a solid intermediate portion and hollow outer portions, said outer portions extending above and below the upper and lower faces of said intermediate portion whereby to provide a longitudinally disposed channel on the upper and lower sides of each block member, the width of each of said outer portions being substantially equal to one half the width of said channel, and a jointing member engaging in the confronting channels of opposed block members having a length equal to the length of a block member, the jointing members of adjacent blocks being disposed in end abutting relation and each jointing member having a thickness substantially equal to twice the depth of a channel in a block.
